Replacement / accessory kit for HYDRA Rainmaster Trio multi-stage rainwater filtration units. This kit includes a stainless steel cartridge plus two 2.5″ × 10″ filter cartridges, clear filter bowls (sumps), 3/4″ NPT connections, wall mounting bracket, and a spanner (wrench).
Intended for use with HYDRA Rainmaster TRIO models having 3/4″ NPT connections.
Filter bowls (sumps): PET (clear) :contentReference[oaicite:15]{index=15}
O-rings / seals: EPDM (typical for housing seals) :contentReference[oaicite:16]{index=16}
Drain / valve / fittings: brass or stainless parts as needed, compatible with NPT threading :contentReference[oaicite:17]{index=17}
Threads (IN/OUT): Stainless steel or brass inserts in the head for NPT connections :contentReference[oaicite:18]{index=18}
Flow performance:
Working capacity: the TRIO series kits are sized to meet specified flow demands while maintaining filtration quality (manufacturer datasheet) :contentReference[oaicite:19]{index=19}
Pressure drop vs flow is characterized at 20 °C, 3 bar in catalog charts for Δp vs l/h performance curves :contentReference[oaicite:20]{index=20}
Dimensions & physical properties:
Total weight: ~6.69 lb (kit listing) :contentReference[oaicite:21]{index=21}
Height / main body: ~390 mm (≈ 15.35 in) in some TRIO models (catalog) :contentReference[oaicite:22]{index=22}
Depth / face dimension C: ~107 mm (≈ 4.21 in) in model charts :contentReference[oaicite:23]{index=23}
Width / lateral dimension B: ~336 mm in some cataloged TRIO units (multiple stages) :contentReference[oaicite:24]{index=24}
Certifications & compliance:
Units in the HYDRA / Atlas Filtri line are certified for drinking water structural integrity, NSF/ANSI 42 (material safety), 61, and 372 (lead-free) in many housing variants :contentReference[oaicite:25]{index=25}
Accessories / mounting:
Bracket included for secure wall mounting of the filter head and assembly :contentReference[oaicite:26]{index=26}
Spanner / wrench included for opening / closing the filter housing (for cartridge replacement) :contentReference[oaicite:27]{index=27}
Drain / blowdown tap or valve interface provided to purge debris collected by prefilter stage (manual or automatic drain kit possible) :contentReference[oaicite:28]{index=28}
Maintenance & service:
Prefilter (stainless steel net) may be back-washed or flushed periodically to eject captured debris, either manually (via drain valve) or by optional automatic kit :contentReference[oaicite:29]{index=29}
Secondary cartridges should be replaced when pressure drop becomes unacceptable or per manufacturer schedule
O-rings should be lubricated (with suitable food-grade lubricant) and inspected / replaced at each service event
Keep clear sumps clean and inspect for cracks, leaks, or clouding affecting visual inspection
Technical & Performance Notes
The HYDRA Rainmaster Trio design provides a three-stage filtration approach: primary self-cleaning net, secondary sediment refinement, and tertiary treatment (carbon / adsorptive stage) to improve rainwater quality. :contentReference[oaicite:30]{index=30}
Because this kit includes stainless steel cartridge and two standard 2.5″ × 10″ filter elements, it aligns with the TRIO head and clear sump housings for modular replacement use. :contentReference[oaicite:31]{index=31}
The clear sumps allow visual monitoring of sediment accumulation within filter stages, aiding timely maintenance. :contentReference[oaicite:32]{index=32}
Operating the system at or below specified pressure and temperature ensures housing integrity and preserves seal life. :contentReference[oaicite:33]{index=33}
Proper installation of bracket, alignment, and tight sealing is crucial to avoid leaks and maintain filtration efficacy.
When replacing cartridges, follow manufacturer torque / tightening instructions (often using the included wrench) to avoid damaging housings or O-ring seals.
